Botanical Time Travel:

Viewing the Past with Modern Techniques and Historic Plant Collections

Jordan Teisher

Herbaria – library-like collections of pressed and dried plants – have informed studies of plant diversity for hundreds of years. These collections still serve many of the same purposes for which they were originally established, including identification, new species discovery, and biodiversity surveys. However, new techniques in molecular biology, stable isotope chemistry, and “big data” computation have made use of herbarium specimens in ways their collectors could never have anticipated. Learn about the rapidly expanding roles played by plant collections in ecology, environmental science, and biodiversity studies.

About the speaker: Jordan Teisher is the Collection Manager for the Botany Department at the Academy of Natural Sciences of Drexel University. A native of central Pennsylvania, he did his undergraduate in Biology at Moravian College. He joined the Academy staff in the summer of 2016 after completing his Ph.D. at Washington University in St. Louis where he studied evolution and systematics in the grass family, Poaceae.

May’s Science on Tap is hosted by the Academy of Natural Sciences of Drexel University.
